I have BANS and I was going to hire another BANSer to create the jpg logo for me. Is there anything that can be hidden in the jpg that would hijack my sales or track what was happening at my site?
I would say no, as long as you have the physical file. In other words make sure the source (img src=) is not going to a site/server that you don't control. If you receive the physical .jpg, etc.. you should be fine. I know there are EXIF METADATA that can be embedded within images.. but that pretty much information about the image itself, so I'd say you are safe. hanji
Yep, hanji is right. When you pay for the logo, have the person email it to you or give you the URL so you can d/l the image to your computer. Then you can upload it to the correct folder in BANS and you're done. Don't let the graphic artist upload it for you! If you need help, PM me.
I was reading the other day about this as I need to implement a .jpg upload feature for a website I'm working on. Apparently php snippets can be inserted into jpg metadata to potentially gain access to your server. To be on the safe side, check the jpg in a program that displays any embedded comments in it. Or if you want to be ultra ultra sure, you could display the logo on your screen, take a screen grab using a paint package, and crop and save your own version of the image to upload.
