I found reference to this elsewhere and changed the settings as follows:
;mssql.textlimit = 2147483647
; Valid range 0 – 2147483647. Default = 4096.
;mssql.textsize = 2147483647
Unfortunately it didn’t seem to make a difference.
I think this is the right track though – it’s some sort of restriction in php or SQL. I thought maybe it’s a timeout issue but the images load fairly quickly – faster than the timeout threshold. Seems like if it was due to SQL setting that there would also be problems with the application display – I think…
