[Bug]: AssertionError: Can't scale by because no image is selected

[bobpuffer1]

Is there an existing issue for this?

• [X] I have searched the existing issues and checked the recent builds/commits

What happened?

Cannot use regular img2img upscale for 4x of 512x768 picture. If you select an image for the img2img tab and then go to the batch tab program autodetects size of image but still gives the error. Selecting Size to limits both dimensions to 2048. To do a 4x upscale of a 512x768 you would be limited to Extras batch which gives A LOT LESS control

Steps to reproduce the problem

1. img2img
2. batch tab
3. input directory parameters
4. choose Scale by and set to 4 (we want a 4x upscale of a 512x768 picture)
5. make all the rest of your settings
6. Generate
7. get error "AssertionError: Can't scale by because no image is select

What should have happened?

Either Scale to should allow larger than 2048 dimensions or Scale by should honor the image in the img2img tab.
