The size required of the photos and the fact that each photo has to be different for each gig is insane. Not all of us take tons of pictures of ourselves or have a bunch of creative photos sitting around of the gigs we are offering to do. Please consider changing your photo policy because it has been nothing but a pain for me. My gigs are about writing or editing, not taking perfect photos.
Chrissy, insane seems more than a bit harsh. You can always use a tool online like a “Meme” maker or the like. I make my images in Microsoft Powerpoint.
And even just changing then the title will make it a new picture.
