Q: Hi, - If I purchase one code with 15,000 credits/month and my website has 10 proxy sizes for each image, does each proxy size use one credit?
- If I upload and optimise images that use the 15,000 credits in month 1 and then upload another 2,000 images in month 2, will the images in month 2 be optimised as well or do the images from month 1 consume the allowance?

Please take a minute to read these articles on how the credits are used for our 2 plugins:

If you're using ShortPixel Image Optimizer (SPIO) then the images that were once optimized will remain optimized. Next month, with the 15K image optimization credits you'll be able to optimize a new batch of images.
