No matter what you do the data will be in the flash memory and therefore affect the "sketch size".
However on an ARM constants should not be copied to RAM, have you verified that indeed 75k of RAM is used by the data?
thanks for your response, i would normally agree with you that everything is stored in flash as so should affect the "sketch size" but i experimented a dozen times where i changed a "char" to a "const char" and saw the sketch size increase by the number of words within my variable, and if i change it back from a "const char" to a "char" the sketch size decreases back to the original size. i am not sure if this is a bug in the IDE or not, but i thought i would point it out.
as i am only familar so far with the 8-bit arduinos, i was not aware that ARM processor constants are not loaded to RAM, this is great to know
i have "verified" the size by removing all the web-page html code, compiling, recording the sketch size, adding the html code back in, compiling, and comparing the new sketch size.
