I cannot fins a website to convert my pics to 1100x250? Why can’t I upload a pi, so I can start selling my product?
I would offer to help you however, my ability to instruct is lacking. I would suggest that you avail yourself of the graphics art services that are offered on fiverr. Someone should definitely be able to help you size your images for a reasonable fee. Also, as a newbie, please read as many of the forum posts provided for you, as you can. TC
