After a year shooting pics, saving them on my pc, uploading them on the forum image gallery in my album and pasting them in my posts using the IMG button... one day it didn't upload my pics anymore. All the others members are fine.
I tried with another pc, I tried from another location, I tried from another location with another pc. No way.
I registered as a new member .. no way.
And other members can upload in my album (I gave them my password, just to try.)
I now can only upload pic that are less than 100kb in size.. if I try something bigger.. the page goes blank.. no error messages.. nothing

Technical infos.
My pictures are on my pc with a size ranging from 200kb to 900kb, 2160 x 1440 pixels, but once uploaded, the system automatically resizes them to a standard 500 x 334 pixels for a size ranging from 20kb to 30kb.
On the statistics in the admin panel I read:
my pictures average size is 28kb. The members average size is 38kb and few members have an average size of 70kb.
So, I don't think that the size is an issue. I post more pictures than them, but again I don't think that the number is a problem.

On the invision gallery panel, I found a tool ..
It says: number of resizing per cycle = 100
Is this the limit for... my resizing? Under that there is a button saying: start to resizing images? What happens if I click on this button? I don't want to affect my members pictures.
I tried to change the number to 200, but every time I go back is set to 100. I hoped that "cycle" was the month, but now is April and I still can't upload pics.

Sorry for my long message, but I wanted to provide all the infos useful.
Be patient: the previous admin quit the forum and gave me the role, without any instruction... and this is not a Gameboy, it's a Boeing 767 without manual..
Thank you for any help.
