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
- In GIMP, choose to save as a JPEG. You should see a dialog box.
- Adjust the quality as high as possible until it's just under <150kb.
Compression in Photoshop
- Go to File>Save for Web & Devices
- Change the file type to drop down in the drop down box
- 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 on. The optimized format provides a 2%-8% reduction of the image file size, so there is no reason for not use always this setting when not using the progressive format.
- Save File
- Hit save to finish.
