my sympathies that you are still having trouble loading bigger pix - I use IrfanView for resizing - down to 700 pixels on the long measurement from the original camera size of something like 3050 - then Picasa for editing contrast and colour. IrfanView is a free download and is really useful.
Looking at your glass, I don't see anything to suggest either nouveau or deco - two artistic styles that are very different in appearance as am sure you're aware - the former originating during the last quarter of the C19 and continuing a little into the C20 and influenced by Continental art, and the later deco style which had it's origins in the period between the two wars, and again influenced by Continental avante garde fashion. Provided something meets the artistic criteria of one or other of these styles, it can be called nouveau or deco even if it was made yesterday - it's all about what something looks like - but people being people usually want period style, so they'd prefer nouveau that was made in 1890 and deco made in 1930. Which is fine, provide we appreciated this does affect the value

Your glass is attractive, and I'd suggest very modern - which is reflected in your comments about the condition - but my opinion is that style wise it has nothing to do with deco or nouveau.
