From: Rivergull on 20 Sep 2009 01:51 A newbie to this, I have to say this particular thread has been very educational. As a long-time film shooter with a manual SLR, I'm finding it a constant challenge to live in the digital photography world. Intending to buy a Leica D-Lux 4 (serious baby), I decided to first get acquainted with digital via a 'mom n' pop' Canon A590IS. First of all, I have an aging PC (Windows XP) with limited memory and no card reader...only USB. Well today my USB ports stopped working (time to get a MacBook PRO!!). With 30 new images in my camera and no way to upload them, a friend volunteered her Dell laptop (Vista) with a card reader. I uploaded the proprietary Canon software, inserted my SanDisk 2GB memory card, uploaded the pics, and emailed them to myself (it didn't work, but that's another story). I removed the memory card from her laptop, inserted it back into my camera...and proceeded to check the images via the LCD. Some (maybe all) are there, but between images I get the message 'incompatible jpg' with a question mark. I can't tell if this indicates a lost image or not, because I can't remember every single image that I shot. QUESTION: Did I really lose images? and without a working USB at home, what would you suggest I do to get the remaining images off the card? Should I go to a place like Staples and ask them to upload the pics onto one of their PC's and save them to a large thumb drive? or to a CD? I know they won't email them...that's not a service they provide. And should I use 'write protect' now, with those 'incompatible jpgs' in there? Aarrgghh! I loved film photography ;o/

USB card readers are about $30.

You don't need Canon's software to read images off of the memory card. You can just treat it as an external disk and copy the files. > I removed the memory card from her laptop, >inserted it back into my camera...and proceeded to check the images via >the LCD.

I'm guessing that the "incompatible" ones are thumbnail images. > QUESTION: Did I really lose images? Unknowable. It depend upon what you did. But probably not. > and without a >working USB at home, what would you suggest I do to get the remaining >images off the card? USB cards for PC are pretty cheap. Under $20. If it's not a software issue then you could try putting in a new card. > Should I go to a place like Staples and ask them >to upload the pics onto one of their PC's and save them to a large thumb >drive? or to a CD? That'd work too. > I know they won't email them...that's not a service >they provide. And should I use 'write protect' now, with those >'incompatible jpgs' in there? Aarrgghh! I loved film photography ;o/ But at $1 per picture, good or bad, it cost a bit more. -- Ray Fischer rfischer(a)sonic.net

Well, yes, but I was thinking about a multi-format reader supporting USB 2.0 high speed and of decent quality. -- Ray Fischer rfischer(a)sonic.net

I loved film photography ;o/ Get some new cards. Don't touch the one you have now until you get your new Mac. You should be able to off load every thing that's there, and make sense of what you have. -- John McWilliams

Gold plated and with diamond studs in the top? Even in the UK where we are seriously ripped off for hitech goods it is hard to pay more than about �10 for a decent multistandard USB2 card reader. The cheapest full spec USB2 units are about half that. I would not expect to pay more than the same number of dollars in the US. Anyway the OP seems to need a new USB2 peripheral card since it is his USB ports that have stopped working (also about a tenner). Hard to say whether images were damaged by the other computer. Other possibilities are that rotating them would make the aspect ratio confict with the cameras display - and some software adds spurious files to media that it is asked to browse (PSPros *.JBF Dozes *.DB for instance) I have never seen one that adds a bogus file for every original image.
