feature: caption type change instantly

[kalle07]

first, all in all for free its a great tool !!!

okay you have some pre option to choose

at the moment i edit the gui file to optimize the input for my images.
eg on a portrait like "tell me the age of the woman"

but every time i edit the file i must restart the programm

may you can implement an re-read with a button.

or you can implment an empty box where i can write what i want
eg "Write me a description of the image, in detail explain ... "

THX

some bug are happend when the image is very simple and i choose "long description" -> its start to copy same words in the captions
watermarks and jpg artifacts are too often recognized where none are present
