Hello michlrp; My advice to you is NOT to ignore the warning - but certainly to take note of it… What matters to BookSmart is pixel count; and Blurb work on the optimum of 300dpi for assessing image sizing… (I "think" that the warning sign starts to pop-up when you get to about 150dpi !!!) If we start with an assumtion that your 35mm image scans are from 6" x 4" prints, and that you scanned at a regular 300dpi, then… Although you will have lost some image quality on the conversion / compression from TIFF to JPEG, you will not (should not!) have lost any sizing… So, if my assumptions are correct, your images will have a pixel count of c. 1800×1200, which, when printed at 300dpi will (re)produce an image of 6" x 4". You need to note that your JPEG image will now be at least a fourth generation copy, so the quality will be much reduced from your original image… However, you should still be able to reproduce the image at 250dpi which will give you c. 7" x 5"... which SHOULD be OK for your 7×7 book project… So, that leads me to believe that one of my original assumptions must be wrong, and I suspect that it’s the scanning resolution… If that’s the case, then I suggest you re-scan your images at a much higher resolution – say 600dpi, which will generate a c. 3600×2400 pixel image. That will give you plenty of lee-way to work with in a 7×7 book, and will help with the quality loss… Holler out if there’s more input you want – but I hope this points you in the right direction… Good luck; Lee
