@Franki. I use
Lunapic and below is my tute:
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.
It's free and you don't have to sign up to use it. I also use Lunapic to manipulate images I find on the net, such as resizing or cropping.
