Black background on details and categories screen

A student with an Android 4.2.2 Samsung Galaxy GT-S7583T always gets a black background at the details and categories screens:

Might be due to relatively low RAM (0.75 GB). Black background is better than crashing, so it is not high-priority. That phone should definitely be able to load the picture though, so we are probably trying to load it in a memory-inefficient way (I assume the same pictures show up fine at the same size in the Android stock gallery). Actually I got this same problem when trying to upload a very heavy picture.

I left it sitting on the category search for hours once, and the picture never showed up there...

I'm the student who encountered the problem; I'd be interested in helping out, if possible, and help test issues :)

I feel that downsampling and resizing functions of fresco, given here, can solve this issue. For example, my screen resolution is 720x1280 and the maximum resolution of my camera is 3280x2160. Knowing this I should be able to resize the image without any loss in quality of the displayed picture, right? Or am I getting this wrong somewhere?

Thanks in advance!

Resizing is definitely the best way to solve this problem, indeed.
This background image feature might be removed in the future (see #1044), but if it is easy and safe then feel free to implement it @harisankerPradeep :-)

@nicolas-raoul From what I can see in the fresco docs it seems simple and safe. I'll post some updates soon enough.
