What's the url you tried?
.../libCachedImageData/c2dbfbc0-f0be-11e9-b656-ad033e7623b7.html this looks like you didn't try to download an image but an html page.

@renefloor We used the following url - https://c.cfjump.com/Products/33681/72414727.jpg

[renefloor]

When I try to load that exact url it just loads perfectly fine, so I don't know what is going wrong. Maybe you once had a 404 page which returned a 200 with an html page instead of a 404 or something like that and than the page is cached.

[gowtham2809]

@renefloor Yeah, there are some chances for that to happen. The image is being hosted behind a CDN like Cloudflare which is returning an HTML to check the caller. Something like this.

Will this library be able to handle that?

[wsakka]

@gowtham2809 and @cgowthamanmca , there is no image library built to handle this situation (it's not an HTTP redirect). Image assets should be stored at a proper CDN like S3, especially when you have CloudFlare's DDOS protection enabled.

@renefloor Do you have a suggestion how to handle the sitiuation when you don't know if the url really returns image data. If there is something wrong with the response I would expect the errorWidget to be loaded.
