你理解正确，它可能会影响分辨率，或者更糟糕的是图像质量。我能提供什么建议？宣布，立即生效，不再允许上传图像。也许它会伤害你网站的吸引力，但我不在乎。 :-)

You understand it all correctly, it may hurt resolution, or worse, quality of images. What can I advise? Announce that, effective immediately, uploading of images is no longer allowed. Perhaps it will hurt attractiveness of your site, but I don't care. :-)
