Problems with thumbnails

[charo]

Good afternoon, first of all apologize for my English since I use Google translator, my question is this, then upload the pictures and creates thumbnails see in the FTP folder that I created 3 sizes for each photo thumbnail example
phoca_thumb_l_afiches_finales1.jpg, phoca_thumb_m_afiches_finales1.jpg, phoca_thumb_s_afiches_finales1.jpg and not how to make me think one size only. Look through the options and does not tell me and the vine component Joomla 1.5 I created a miniature one.
Also try deleting and leaving only the thumbnail m to me frontpage thumbnail disappears.
I would like to know if there is some kind of solution for this.
From already thank you very much

Hi, all 3 thumbnails must be done as all of them are used.
