BakaBT only allows images for descriptions that are <150kb in size. If your image is over the limit, you'll have to compress it to a file size that's acceptable.

JPEG Compression

JPEG is a format for lossy compression of images. This is the simplest and most wide-ranged used image format for compression.

Compression in GIMP

  1. In GIMP, choose to save as a JPEG. You should see a dialog box.
  2. Adjust the quality as high as possible until it's just under <150kb.
    Dialog Box



Compression in Photoshop

Save for Web & Devices in Photoshop
  1. Go to File>Save for Web & Devices
  2. Change the file type to drop down in the drop down box
  3. Adjust the quality to find the right file size (Look at the bottom left under the preview)

File Type
Drop down to choose the file type for the image. JPEG, PNG, BMP, etc...
Compression
How much quality there should be. The higher the quality, the less compression. The less compression, the bigger the file size.
Final File Size
How big the file will be once you hit save.
Preview
You can preview how the final image will look after saving.
Optimized
It's recommended you have this option turned off. It's not necessary to optimize again it when you're already saving as a JPEG.
Save File
Hit save to finish.
