Missing images in Pocket

[qkqw]

Hey all,

I am relying quite heavily on the Pocket functionality and love to read most of my articles there. Recently I've noticed that some images are missing in some articles.

Investigating further it seems that all jpg images are displayed fine, while all other (mostly png, gif and svg) won't be displayed at all. Instead you'll find an "image missing" icon.

Articles are stored along with their images in

.kobo/articles/[article id]

Here's an actual example with two images, one jpeg and one png:

$ file *
4ca1dc019ebadd67fd8058f58ca1f143: PNG image data, 1000 x 1000, 8-bit/color RGB, non-interlaced
76652588b5ea3e1a96baf8f6036235a1: JPEG image data, resolution (DPI), density 72x72, 746x485
index.html:                       ASCII text, with very long lines (922)

For this article, the first image (png) won't be displayed, but the jpeg one will be. Looking at the HTML code, there is no difference between those two:

<div class="RIL_IMG" style="max-width: 100%; height: auto;"><img src="file:///mnt/onboard/.kobo/articles/1104886005/4ca1dc019ebadd67fd8058f58ca1f143" /></div>

<div class="RIL_IMG" style="max-width: 100%; height: auto;"><img src="file:///mnt/onboard/.kobo/articles/1104886005/76652588b5ea3e1a96baf8f6036235a1" /></div>

Has anyone found a workaround for this issue?

The strange thing is that if you use Pocket's web view, it will automatically convert all png's to jpegs with an url like
