I think I have shared this on another thread about attaching/uploading photos using
LunaPic, but see below:
1. Save your picture to your computer desktop (or somewhere you can find it easily).
2. Use the
Browse folder in Lunapic to find the image you want to upload.
3. You will see that you have options to
crop,
scale or
rotate. If the image is large, pick
scale and reduce.
4.
APPLY the resultant new size.
5. Scroll to the
bottom for the
Save options and click on
Imgur.
6.
Copy everything in the
Image URL window and use the link to repost the image using the picture icon in reply.
I use LunaPic mostly from my computer and there is no app. It's also good for editing pictures found on the web, for example, resizing or cropping.
It's a bit long winded, but don't even have to thing about the steps now.
