These instructions tell how to make classic lolcats, with the proper font and the black border so that contrast is good.
- Open the picture in the GIMP.
- I scale the entire image down to 640x480 or 1024x768, so that the text size is reasonable (with these sizes, the text is around 60-100 point usually)
- Add the text. The "classic" lolcat font is Impact, but feel free to use whatever you want. It is usually white.
- Optionally, crop it down using the crop tool.
- go to the layers dialog (Dialogs menu)
- Duplicate the text layer (click on the layer, hit the duplicate button below)
- Select the bottom text layer.
- Right click on it and do "layer to image size"
- Use the "select regions by color" tool to select the text. All letters should become selected.
Select -> Grow. I grow the selection by 6, but it depends on the total text and image size.
- Select dump bucket, make sure the foreground color is black.
- Dump bucket the selected area. Since the active layer is the middle one, the white text will still show through.
Unselect everything (C-S-a or Select->None) and see if it looks good
- Crop it more if you'd like.
- Save as jpeg.
