I just found this, and this would make my script so much cleaner. Any chance of it making it into a release soon? Thanks!
I'll have to check with the customer. It was generated by Photoshop, but I don't use it, so I can't tell you the steps. I'll see if I can find out.
Interestingly, I found it used in a few Adobe specs without being defined. It's a one-byte length followed by the string, instead of being null-terminated. https://en.wikipedia.org/wiki/String_(computer_science)#Length-prefixed
The name in the Image Resource Block is a Pascal string, so it's limited to 255. The beginning of the query string is 15 characters. Add a trailing null and 271 is the max. (I made it larger than I needed to in case I needed to add more to the beginning, if I recall correctly. Just being a little paranoid) Here's the Adobe specification about Image Resource Blocks: https://www.adobe.com/content/dam/acom/en/devnet/photoshop/psir/ps_image_resources.pdf
