@NicolasRobidoux Thanks for the heads up about Flattr...Cristy has been flattred!

Defiantly better then beer since in 20+ years of using forms only one person has ever taken me up on it!

Merry Christmas everyone!

Thanks again for all the discussion, especially about the what came first the chicken-before or the chicken-after. Basically, I have been 'guaranteed' the before (320x240) is the real before and the after (640x480) is really the after. The reason, the real estate board only sends out the 320x240 ...

Snibgo: interesting idea...currently the photos are coming from a real agent via a feed. We have been told the restrictions are 320x240 maximum but the the 'after.jpg' is 640x480! So, we assume the after.jpg must have come from come from the 320x240 image. Unsharpen is helping a bit but the red ...

Snibgo: Thanks for the feedback. I will try the unsharp mask and see how it goes. That said, I am 95% sure (but maybe less so now) the before.jpg was used to produce the after.jpg. Is there a 'very intelligent program' that can do this kind of scaling up? Beside imagemagick... Once I test unsharp, I ...

Hi all, After a day and a half of reading, testing, trying I am turning to the community for some help. I am stumped, thought I was getting close but at this point I am just guessing. And it seems this has been solved many times before. PROBLEM: trying to increase a JPG file from 320x240 to 640x480 ...
