builttospill: this is exactly what I was thinking. dpi definitely has an affect, as well as sensor size.
Photoshop automatically sets commas to semicolons, so alamy seems to be working okay reading mine (from PS CS3) I am not sure about Cushy Stock - I need to check and see on my latest batch if they read alright. I have been keying mostly in Cushy lately. I'll you know what happens.
I've been getting pretty fast at image upsizing the old fashioned way
I just got the script to work- if anyone needs it, here is the code: just save it in a notepad document as alamyresizer.jsx or something similar.
PTWiki | Article - JavaScript script for resizing images to a target file size
Special thanks to Steve Smith on this one!
I have to just figure out how to make the droplet. The only thing is, that it will even downsize images that are larger than 48M back down to 48M. No big deal though, I don't think file sizes larger than 48M really matter on Alamy. Some of my illustrations are 70M. Would I get more money for those sizes? Maybe I could always figure out how to add a line that tells the script to not downsize if the image is already greater than 48M.
