Suggestion for improving image loading

Dear developers,

I am a user of RedReader, and thank you for the wonderful work.

When I click an item and browse it's image, for some large images, the downloading process will take a long time.
For example, the situation below can consume more than 10 seconds:

In many cases images are larger than required. Android documentation suggests us to resize the image according to the size of the UI component that displays it. By properly resizing image before downloading and decoding, we can save memory resource and make app run more smoothly, which can provide users with a better experience.
https://developer.android.com/topic/performance/graphics/load-bitmap.html#read-bitmap

I noticed that in the following code, image resizing is correctly applied:
org.quantumbadger.redreader.views.imageview.ImageTileSourceBitmapRegionDecoder.java getTile()
https://github.com/QuantumBadger/RedReader/blob/master/src/main/java/org/quantumbadger/redreader/views/imageview/ImageTileSourceBitmapRegionDecoder.java#L75

However, in the code below, images are decoded directly without resizing:
org.quantumbadger.redreader.activities.ImgurUploadActivity.java (line number 213)
https://github.com/QuantumBadger/RedReader/blob/master/src/main/java/org/quantumbadger/redreader/activities/ImgurUploadActivity.java#L213

org.quantumbadger.redreader.adapters.AlbumAdapter.java (line number 157)
https://github.com/QuantumBadger/RedReader/blob/master/src/main/java/org/quantumbadger/redreader/adapters/AlbumAdapter.java#L157

I am not familiar with the source code of RedReader, so I am not sure whether the code listed above corresponds to the situation I described. However, whether it is or not, I think they all need to be optimized.

Do you think image resizing will improve RedReader' performance? If yes, perhaps resizing image before downloading can make RedReader more smooth in user interaction.

Looking forward to your response.

Thanks.

Start with getTile() in org.quantumbadger.redreader.views.imageview.ImageTileSourceBitmapRegionDecoder.java, then inspect the direct decoding at lines 213 and 157 of ImgurUploadActivity.java and AlbumAdapter.java. Determine whether those paths match the reported large-image delay; done means the relevant images are resized before downloading and decoding, with the loading behavior verified against the report.
