What is the file size limit?

What is the file size limit of file which i pass to src.sencha.io?
When i trying to resize my photo (jpg ~1.5mb and more) i got 404 error. With smaller sizes all is ok.

Are you trying to use the base64 encoding option?

mitchellsimoens, no.
This is image on rghost.net http://tau.rghost.ru/36662029.image
This is sencha.io link http://src.sencha.io/320/200/http://...36662029.image
And it doesn't work.

No. This link:

sencha: src.sencha.io/320/200/http://rghost.ru/36674508/image.png
Other image hostings do the same results with this file.

There is no limit to add file size.

There was no previously documented upsteam image size limit. There was however silent failures when the upstream image was "too large" to process without timing out. With the migration to the new implementation in process, we have put in place an upstream image size limit of 20M and proper error handling for larger images.

i too had a misconception that there are limits for size cause i also saw these warnings of size too big so couldnt upload pics as it took a very long time..
