    Why PDF limit of 100K?
    Can we up this to allow for PDF's with images?

    I posted a work-around only yesterday, if you only wish to post a page or three from your document. Bursting pdf files for their contents is a messy process mostly best avoided. The trick is to retain reasonable image quality.

    pdf is closely related to the drawing "language" used by postscript printers. I use the print to file function to print the .pdf pages needed to a .ps postscript file.

    This file is input to imagemagick, which converts it from drawing instructions to a forum-friendly image format at high density (say 300 - 450 dots/inch). The image can be rotated and clipped as desired, and usually then compressed to forum limits, either by imagemagick or an image program. I often do the further manipulations in imaging software, such as gimp.

    The process is easily automated in a simple script or batch command.

    Imagemagick runs from the command line of most systems, inc Windows - ImageMagick: Convert, Edit, Or Compose Bitmap Images. Linux users have some alternatives already built-in to the command line, as these are postscript systems.

    A pdf to postscript printer is an easy job that most pdf software can handle.

    Archiving whole documents in a special section would be useful at times.



    PS: Putting pdf and ps files direct into your imaging system (if it can read them) can lead to severe loss of pixel density. The density step above is important. The imagemagick command used for my post yesterday was: convert -density 400 shiftlock.ps shiftlock.png

    PPS: If you only want to break a page out of a long pdf, and that will fit, the simplest tool is pdftk, another free Linux tool now available for Windows for a small fee - https://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/

    It'snot so much the work the "work around" it's the inconvenience of having to manipulate a perfectly good pdf to only post a few pages.

    Snipping tool on windows is fast for most people. Of course the file can be put up on image shack or similar.

    IMO 100k is very small file.

    It's a pest having to do it Rob, but scripting has made it trivial. Snipping tools lose the printer pixel density which is usually present in the pdf. The sole purpose of the postscript fiddle above is to preserve image density and definition.

    A forum size increase would certainly help if the storage is available.

    I'll investigate forum file size and see if we can lift the limit ( I can't see the limit being raised to several MB though), an interim solution is for users to open a Dropbox account (FREE) and create and share a 'Froggy Files' folder - post a link to the folder in your reply.

    It's well and good if you run a linux OS. However most don't nor will they bother to learn scripting language or arcane command line procedures.

    The post script procedure is a good one but a real pita.

    And what about the forum users who access the forum via a android or apple app?

    Sensible storage sizes is the best option.

    G'day,

    AF has a meg allowable if you ZIP your file/s....

    the version of PDFTK I use here, on windoze, is a freebie, adds PDFs together and dismantles, great program.

    PDFexchange viewer is also a freebie, this will export pages to images of a specified quality, another good 'un.

    they even work on XP.....

    cheers,
    Bob

    That's odd

    I can't remember ever seeing any advertising, it might have been there but as I'm only interested in downloading the file I'm after I can say I've never noticed anything??

    I guess FREE comes at a cost

    G'day Rob,

    can't say that I've noticed a lot of ads on dropbox, aaaah, or here....

    maybe a function of using freebie adblock plus ?

    cheers,
    Bob

    Rob I wasn't out to convert. Linux users mostly need no help. It was simply a Windows workaround using free software. Script=Windows batch file in this case. Bob has found and endorses pdftk, and it's a beaut tool to have.

    I agree with you that it would be better to be able to upload more. I'm not enamoured of Dropbox.

    I am not up on tablet apps enough to give example apps, but the method holds.

    G'day Greenblood,

    when I attached ZIP files in the past they came up as a little icon and data
    Download links for manuals, tech data etc
    now they come up as text
    Download links for manuals, tech data etc - Page 2

    am I doing something wrong..... ?

    cheers,
    Bob

    Hi Bob,
    I'm not on top of the forum software upgrades, thankfully Gerry (gibgib) takes care of our technical issues.

    I see what you mean but in both cases I can download and open the zipped files, in your first link yes you see a zip icon - It may be rectified with the next software upgrade? We seem to win some features and lose others with each bug fix. . .

    Sorry I can't be more helpful

    Cheers
    Chris

    Bob, the markup sent to the browser was as follows:
    <div id="post_message_1315374">
    <blockquote class="postcontent restore ">
    G'day,<br />
    <br />
    this one was donated by Sunroof, gearbox &amp; engine combinations.<br />
    <br />
    Thanks mate.<br />
    <br />
    <a href="http://www.aussiefrogs.com/forum/attachments/renault-forum/64487d1420348633-download-links-manuals-tech-data-etc-gearbox-specs.zip" title="Name: Gearbox Specs.zip

    <br />
    cheers,<br />
    Bob
    </blockquote>
    </div>
    so what you see is what the forum software intends when this message is called up. No image was included within the link anchor <a>.......</a>

    ps: If it's really important, look for a Link Alert user javascript for your browser. These scripts insert a file type icon.

    G'day seasink,

    nope, not that important, just that the posting system works a little different to what it used to. The oldies, which are still there and effective, were in this style.....

    ............
    <li>
    <img class="inlineimg" src="http://www.aussiefrogs.com/forum/images/aussiefrogs/attach/zip.gif" alt="File Type: zip" />
    <a href="http://www.aussiefrogs.com/forum/attachments/renault-forum/25246d1327447889-download-links-manuals-tech-data-etc-fuegoausupplement-small.zip">FuegoAUsupplement-small.zip</a>
    (693.9 KB, 66 views)
    </li>
    .............
    which created the little icon, see, you can teach an old dog....

    cheers,
    Bob

    That's what the user browser javascripts you can find online do. When they encounter the link, they look at the file type and if there isn't also an image, add the appropriate icon image from their collection (.exe, .zip, .rar, .pdf, txt, etc). It would appear that the forum code once did this too when the link was posted, hence the oldies.
