Just for accuracy - I think your solution is not the real answer to the question you've asked initially.
Probably irrelevant here, but you said you'd want to check if the image exists _before_ downloading it. In your code, you download it and _then_ check if it exists.
If downloading is the single option, you're code is OK. But if you'd want to avoid say images bigger then 2 GiB, you're code would waste bandwide, downloading the images and then disposing them.
To actually just check for the existence of an image, you'll want to use $ua->head($image) instead of $ua->get($image).
Just in case that could matter.
