hey @beingthere , SCF isn't letting me reply to any private messages & can't seem to figure it out. But to answer your question i get all my images for 8x10's from Google or Bing & just search "Large" to get the highest resolution images possible ( Atleast 1000 x 1000 ) . I usually us the photo mailers you can buy @ walmart ( 9x12 ) & use 4 forever stamps for that. Its a bit over but i have had in the past, a driver has added a hero card. I also use the 10x13 manila envelopes from Walmart to send everything in. I usually take all of it to the post office to have it weighed & then ship from there. If you have anymore questions LMK here or leave an email & i can send you some Zilisch photos that will work for 8x10's.
