this is driving me insane please can anyone help please !!!!!!!!!!!

Uploading photo's is fine no probs its the text that is added to them before posting
its sending my gallery way wide ( see pic below )

Is there a way to size the box so it can only go so far before starting a new line
to keep the gallery looking decent ... at the mo it looks Ukkyyyyy

Not sure i am explaining myself properly but the pic below should help ...

Any help much appreciated oh and by the way i am so NEW to this if its complicated
can i get detailed instructions pretty please

Option 1:
Edit your style sheet accordingly - make the wrapper class truncate/crop the text

Option 2:
Edit your theme, crop the text that goes into the description
